exit() is a libc function, which is why you can't find it.

If you wrap MPI_Finalize() in a DLD-FUNCTION, you can
register it with a call to the octave function atexit so that it
will be called when octave exits.  This you can do from your
initialization code so hopefully you don't have to modify
octave to get it to work.

If your initialization is happening in a DLD-FUNCTION,
then you will need to call atexit using something like the
following:

   octave_value_list atexitargs;
   atexitargs(0) = "MPI_Finalize";
   feval("atexit", atexitargs, 0);
